Equilibrium Question 651
Question: 3.2 moles of hydrogen iodide were heated in a sealed bulb at $ 444^{o}C $ till the equilibrium state was reached. Its degree of dissociation at this temperature was found to be 22%. The number of moles of hydrogen iodide present at equilibrium are [BHU 1982]
Options:
A) 2.496
B) 1.87
C) 2
D) 4
Show Answer
Answer:
Correct Answer: A
Solution:
